* ffmpeg: Ignore SIGPIPEMark Thompson2018-01-251-0/+3
| | | | | | | | | | | | | On systems which deliver SIGPIPE (Unices), a broken pipe will currently result in the immediate termination of the ffmpeg process (the default disposition as required by POSIX). This is undesirable, because while the broken pipe is likely fatal to useful cleanup of whatever component is writing to it, there might be other components which can do useful cleanup - for example, a muxer on another stream may still need to write indexes to complete a file. Therefore, set the signal disposition for SIGPIPE to ignore the signal - the call which caused the signal will fail with EPIPE and the error will be propagated upwards like any other I/O failure on a single stream.

* | avformat: add option to parse/store ID3 PRIV tags in metadata.Richard Shaffer2018-01-245-1/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Enables getting access to ID3 PRIV tags from the command-line or metadata API when demuxing. The PRIV owner is stored as the metadata key prepended with "id3v2_priv.", and the data is stored as the metadata value. As PRIV tags may contain arbitrary data, non-printable characters, including NULL bytes, are escaped as \xXX. Similarly, any metadata tags that begin with "id3v2_priv." are inserted as ID3 PRIV tags into the output (assuming the format supports ID3). \xXX sequences in the value are un-escaped to their byte value.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If codecpar->extradata is not set (for example, when the stream goes through the 'tee' muxer), then a segfault occurs. This patch ensures the data variable is not null before attempting to access it Before the var_stream_map option was available - I was using the tee muxer to create each resolution as an individual stream. When running this configuration after the most recent hlsenc change I hit a segfault The most simple command which recreates the segfault is: ffmpeg -i in.ts -map 0:a -map 0:v -c:a aac -c:v h264 -f tee [select=\'a,v\':f=hls]tv_hls_hd.m3u8 Signed-off-by: Brendan McGrath <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | During the initialization stage, the codec attempts to get free buffers from the driver before any have been queued (this is to keep the code simple and generic) When the kernel driver detects this situation, it returns POLLERR in revents and ffmpeg therefore raises a warning. This commit disables the warning since no buffers were queued to the driver yet. Signed-off-by: Jorge Ramirez-Ortiz <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Qualcomm's db410c/db820 Venus driver currently present in mainline kernel has a bug which mishandles the CMD_STOP requests causing the decoder to block while draining [1]. This patch removes the workaround that was used to prevent that situation. Encoding/Decoding tested on db820c. [1] on CMD_STOP, the driver is flushing all buffers and never raising IPIPE which ends up in blocking on poll.
