* avformat/http: Ensure same protocol in ff_http_do_new_request2Zhao Zhili2025-04-291-1/+6
| | | | | | | | | | | This can happen for HLS with AES-128 at the middle of m3u8, so old protocol is https while new protocol is crypt+https. And change the log level from ERROR to INFO when protocol/host/port don't match. User should prepared for this function to fail and retry with new connection.

* avcodec/bsf/h264_mp4toannexb: Fix mixed bitstream formatZhao Zhili2025-04-292-12/+14
| | | | | | | | | | | | | | | | | | | | This bsf converts AV_PKT_DATA_NEW_EXTRADATA side data in avcc format to in-band annexb format. However, the side data wasn't been removed and copied from input packet to output packet. So the output packet has mixed bitstream format. We don't support mixed bitstream format. For example, h264_metadata report error in the following case: ffmpeg -i foo.flv \ -bsf:v "h264_mp4toannexb,h264_metadata" \ -c copy -f null This patch removed NEW_EXTRADATA side data after process. This patch also add a check so only NEW_EXTRADATA in avcc format is processed. NEW_EXTRADATA in annexb format is copied to output as is.

* avcodec/webp: Switch to ff_vlc_init_from_lengths()Andreas Rheinhardt2025-04-251-53/+55
| | | | | | | | | | | The earlier code would traverse over the code lengths mutliple times (namely max_length + 1 times - once to get the maximum length and once for each max_length to assign codes) before calling ff_vlc_init_sparse() (which may traverse them twice and sort them). The new code only traverses them once (+ the one time in ff_vlc_init_from_lengths()). Signed-off-by: Andreas Rheinhardt <[email protected]>
* avcodec/webp: Check more directly for invalid codesAndreas Rheinhardt2025-04-251-2/+5
| | | | | | | | | | Don't rely on invalid codes leading to get_vlc2() returning -1, which then gets converted to an uint8_t, i.e. to 255 and runs afoul of a length check later. After all, get_vlc2() could be changed to return something else which may be valid when cast to uint8_t. Signed-off-by: Andreas Rheinhardt <[email protected]>
* avcodec/cbs: Use put_bits63()Andreas Rheinhardt2025-04-251-8/+2
| | | | | | | | | | It is better when BUF_BITS == 64 (i.e. on x64), because the underlying put_bits can then handle 0..63 bits naturally. It does not worsen the code when BUF_BITS != 64, because the compiler can optimize this to the same code as now (due to the assert). Signed-off-by: Andreas Rheinhardt <[email protected]>

* avcodec/vp6: Use fewer number of bits in run VLCsAndreas Rheinhardt2025-04-252-7/+12
| | | | | | | | | Given that these trees have only nine elements and are complete, their depth is <= eight. Also remove the now unused FF_HUFFMAN_BITS constant. Signed-off-by: Andreas Rheinhardt <[email protected]>
* avcodec/vp6: Don't reload unnecessarily often in get_vlc2()Andreas Rheinhardt2025-04-251-3/+3
| | | | | | | | | | | The VLC trees used here have very few different codes and are therefore guaranteed to not be very deep: The AC/DC VLCs have 12 elements and therefore a depth <= 11 whereas the run VLCs have only nine elements and therefore a depth <= 8. This allows to reduce the worst-case number of reloads for reading a VLC code. Signed-off-by: Andreas Rheinhardt <[email protected]>
* avcodec/vp6: Don't initialize unused VLC tablesAndreas Rheinhardt2025-04-252-7/+5
