* ffplay: Fix realloc_texture when input texture is NULL.Matt Oliver2018-04-18
| | | | | | | | | SDL_QueryTexture and SDL_DestroyTexture require that the input texture pointer be non-null. Debug builds of SDL will correctly check for this and break program execution. This patch fixes this by checking the status of the texture pointer. Signed-off-by: Matt Oliver <protogonoi@gmail.com>
* ffprobe: report unavailable SAR correctly in stream infoTimo Teräs2018-04-17
| | | | | | | | | av_guess_sample_aspect_ratio() will return undefined or missing value as {0,1}. This fixes show_stream() to check numerator to display 'N/A' when appropriate. show_frame() does this already correctly. Signed-off-by: Timo Teräs <timo.teras@iki.fi>

* avutil/pixdesc: deprecate AV_PIX_FMT_FLAG_PSEUDOPALwm42018-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PSEUDOPAL pixel formats are not paletted, but carried a palette with the intention of allowing code to treat unpaletted formats as paletted. The palette simply mapped the byte values to the resulting RGB values, making it some sort of LUT for RGB conversion. It was used for 1 byte formats only: RGB4_BYTE, BGR4_BYTE, RGB8, BGR8, GRAY8. The first 4 are awfully obscure, used only by some ancient bitmap formats. The last one, GRAY8, is more common, but its treatment is grossly incorrect. It considers full range GRAY8 only, so GRAY8 coming from typical Y video planes was not mapped to the correct RGB values. This cannot be fixed, because AVFrame.color_range can be freely changed at runtime, and there is nothing to ensure the pseudo palette is updated. Also, nothing actually used the PSEUDOPAL palette data, except xwdenc (trivially changed in the previous commit). All other code had to treat it as a special case, just to ignore or to propagate palette data. In conclusion, this was just a very strange old mechnaism that has no real justification to exist anymore (although it may have been nice and useful in the past). Now it's an artifact that makes the API harder to use: API users who allocate their own pixel data have to be aware that they need to allocate the palette, or FFmpeg will crash on them in _some_ situations. On top of this, there was no API to allocate the pseuo palette outside of av_frame_get_buffer(). This patch not only deprecates AV_PIX_FMT_FLAG_PSEUDOPAL, but also makes the pseudo palette optional. Nothing accesses it anymore, though if it's set, it's propagated. It's still allocated and initialized for compatibility with API users that rely on this feature. But new API users do not need to allocate it. This was an explicit goal of this patch. Most changes replace AV_PIX_FMT_FLAG_PSEUDOPAL with FF_PSEUDOPAL. I first tried #ifdefing all code, but it was a mess. The FF_PSEUDOPAL macro reduces the mess, and still allows defining FF_API_PSEUDOPAL to 0. Passes FATE with FF_API_PSEUDOPAL enabled and disabled. In addition, FATE passes with FF_API_PSEUDOPAL set to 1, but with allocation functions manually changed to not allocating a palette.
* fftools/cmdutils: add support for level flag in loglevel option parserTobias Rapp2018-04-03
| | | | | | | | | | Allows to manage the AV_LOG_PRINT_LEVEL flag as a prefix to the loglevel option value, similar to the existing AV_LOG_SKIP_REPEATE flag. Adds support for setting flags relative to the existing value by using a +/- prefix.

* ffmpeg: prevent premature EOF in sub2video with nullptr AVSubtitlesJan Ekström2018-04-01
| | | | | | | | | | | | | | | | With certain types of input and the filter chain getting re-initialized or re-configured, multiple nullptr AVSubtitles can get pushed into sub2video_update() in a row from sub2video_heartbeat. This causes end_pts, and on the next round pts, to become INT64_MAX, latter of which signals EOF in framesync, leading to complete loss of subtitles from that point on. Thus, check that the sub2video.end_pts is smaller than INT64_MAX in a similar fashion to sub2video_flush before sending out the nullptr AVSubtitle. This keeps premature EOFs from happening in framesync and the subtitle overlay is kept past the filter chain re-initializations/configurations.

* ffmpeg.c - drain all decoded frames during stream_loop flushGyan Doshi2018-03-20
| | | | | | | | | | | | | | When a decoded stream is being looped, after each post-EOF rewind, decoders are flushed in seek_to_start(). This only drains 1 frame, and thus the output has a few frames missing at the tail of each iteration except the last. With this patch, process_input is looped till process_input_packet reaches EOF.

* ffmpeg: Ignore SIGPIPEMark Thompson2018-01-25
| | | | | | | | | | | | | 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.

Future OpenCL use will be via hwcontext, which requires neither special OpenCL-only API nor global state in libavutil. All internal users are also deleted - this is just the unsharp filter (replaced by unsharp_opencl, which is more flexible) and the deshake filter (no replacement).
